Hertel SZ2059OB Abrasive Bur Oval 3/8 Inch Solid Carbide

Product Description

The HERTEL SZ2059OB is a solid carbide abrasive bur with an oval head profile, designed for material removal, deburring, and finishing work in metalworking and fabrication applications. The bur features a 3/8 inch cutting diameter and a 5/8 inch length of cut, delivering consistent stock removal in confined areas where rotary files and die grinders are the preferred tools. The single cut tooth style produces a smoother finish compared to double cut geometries, making it well suited for finishing passes on ferrous and non-ferrous metals. The uncoated solid carbide head provides the hardness and wear resistance needed for demanding machining tasks. The 1/4 inch shank fits standard die grinder collets widely used in machine shops, tool rooms, and maintenance environments.

This bur is used in die grinding, mold and die work, weld blending, port matching, and general metal finishing tasks. The oval head shape allows access to contoured surfaces, radiused pockets, and curved profiles that flat or cylindrical burs cannot reach effectively. It is appropriate for use on steel, cast iron, aluminum, and similar materials in both production and repair settings. Machinists, tool and die makers, and maintenance technicians are the primary installers and users of this type of tooling. The SE-3 TN industry specification identifies the head geometry and shank size class for direct cross-reference in tooling catalogs.

Key Features

• Oval head profile for contouring, profiling, and accessing curved or recessed surfaces
• 3/8 inch cutting diameter with 5/8 inch length of cut for precise material removal
• Single cut tooth style produces a smoother finish and lower heat buildup compared to double cut
• Solid carbide construction provides superior hardness and extended tool life versus high-speed steel alternatives
• 1/4 inch shank diameter fits standard die grinder collets without adapters
• Uncoated head maintains consistent cutting geometry throughout the tool life

Compatibility

Designed as a direct-fit replacement or standard tooling option for die grinders and rotary tool machines accepting a 1/4 inch shank collet, conforming to the SE-3 TN industry specification for oval carbide burs.

Installation Notes

Installation is performed by machinists or maintenance technicians using a die grinder with a matching 1/4 inch collet. Ensure the die grinder is powered off and disconnected from its air or electrical supply before inserting or removing the bur. Tighten the collet nut securely to prevent slippage during operation. Always operate within the maximum RPM rating of the tool and wear appropriate eye protection and gloves when using rotary burs.
